摘要
结合工程实例，详细介绍了低强度等级混凝土桩与振密砂石桩的组合型复合地基。试验研究及理论计算表明，该复合地基能充分发挥两种桩的特点，提高地基承载力，经济效益显著。
Based on practices, the composite foundation with low grade concrete piles and vibro-casting sand-gravel piles is introduced. Experiments and calculation show this kind of base can improve ground bearing capacity and the economic benefit is good.
